As a dependency you'll need the libomxil-bellagio (Arch Linux) or libomxil-bellagio-dev (Ubuntu) package which provides the required header file OMXCore.h. Static ffmpeg binaries for Homebridge with support for audio (libfdk-aac) and hardware decoding (h264omx). For hardware encoding of H.264 (encoder is named h264omx) and MPEG-4 (mpeg4omx). This condition is more prevalent at high bitrates as frames are inherently larger. enable-omx-rpi Enable OpenMAX IL code for Raspberry Pi.
